SASL is the Simple Authentication and Security Layer, a method for
adding authentication support to connection-based protocols. To use
SASL, a protocol includes a command for identifying and
authenticating a user to a server and for optionally negotiating
protection of subsequent protocol interactions. If its use is
negotiated, a security layer is inserted between the protocol and the
connection. See RFC 2222 for more information.

Any of: ANONYMOUS, CRAM-MD5, DIGEST-MD5, GSSAPI (MIT Kerberos 5 or Heimdal

without the SASL plugins. Most likely you will need to install the
libsasl2-modules package.
